Named in honor of Matthew P. Golombek, research scientist in geology and planetary geology at the Jet Propulsion Laboratory. He has devoted the past five of his 14 years there to the Pathfinder project, distinguishing himself by his highly effective performance as the Mars Pathfinder project scientist, responsible for all aspects of the mission’s science. The discoverers wish to salute this popular spokesman for his understandable science and Pathfinder mission status reports. His descriptions and explanations captured the attention of a public excited by the Mars landing and the rocky excursions of the small rover, Sojourner. (M 31024) _ _.
